Question

0.1,0.2,0.3,0.6 are in proportion or not

Answer 1

Yes they are.
Taking the ratio of 0.1 and 0.2
$\frac{0.1}{0.2} = \frac{1}{2}$
Also taking the ratio of 0.3 and 0.6
$\frac{0.3}{0.6} = \frac{1}{2}$
Even if you take the ratio of 0.1 and 0.3 OR 0.2 and 0.6 you will find that they are in proportion.
Hope this helps... :)
